I don't think that True Orthodoxy is as small as it might seem at first glance. True Orthodox groups don't get the money, or the media coverage, nor do they have the political clout of World Orthodoxy. As was pointed out above, we have made a conscious choice not to follow the ways of the world. We recognize that to a great extent we live in a post-Christian society, with no place for True Orthodoxy. Unlike World Orthodoxy, we don't think that we can influence today's world, and we don't strive to conform and be a part of it. Consequently, even in places where we are not actively persecuted, we are mocked and slandered, or, at best, ignored.
But all over the world there are communities of Orthodox Christians struggling to practice and to preserve Traditional Orthodoxy, as the Holy Fathers teach it. Just in answer to your query you were given the addresses of a monastery and 2 parish communities within traveling distance from where you live. While there are some "extreme" extremists within True Orthodox groups that might insist that their particular small group is all that remains of the Orthodox Church, most of us see True Orthodoxy as a larger, loose federation of small groups, that might not belong to one jurisdiction, and might not be formally in communion, but are nevertheless striving for the same thing.
Neither is World Orthodoxy as large, united and monolithic as might seem at first. Scratch a little below the surface, and you'll find plenty of factions and divisions, and power struggles, such as the one between the Patriarchates of Constantinople and Moscow. I feel that the idea of one large, united Orthodox Church that World Orthodoxy now so actively pushes is to a great extent a myth. Throughout history, more often than not, the Church was small and divided. As was also pointed out above, it's not about numbers. "Fear not, little flock", our Lord said, and He foretold that those that seek the Truth would be misunderstood and persecuted. And "Will I find faith when I return to the earth?" He asked.
You also have to realize that we're not involved in some competition or "popularity contest" with World Orthodoxy, either before the eyes of God or the world, as to who is "bigger", "better", etc. I think that in this day and age it is probably providential and ultimately better for us to be a series of loosely connected small groups, then a large, monolithic body. This will make it easier for us to survive when real persecution comes. We strive, in the words of St. Philaret, to "hold fast to what we have", to hold on to the Pearl of Great Price that we have been entrusted with.
